ICD-10 Code H05.422 – Enophthalmos due to trauma or surgery, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H05.422 – Enophthalmos due to trauma or surgery, left eye
What it is
H05.422 identifies posterior displacement of the left eyeball caused by trauma or surgery. Use it when the record clearly links the enophthalmos to an injury or postoperative change.
Clinical signs
Typical findings include a sunken appearance of the left eye and asymmetry of the orbits. Clinical features vary; refer to documentation for the exact cause and laterality.
When to use this code
Use this code when the provider documents left-sided enophthalmos as a result of trauma or a surgical procedure. It is appropriate for postoperative or post-injury follow-up when the condition itself is being assessed. Check documentation if the cause or eye laterality is not clearly stated.
Do not use for
Do not use it for enophthalmos without a documented traumatic or surgical cause. Do not assign it for the right eye, bilateral findings, or unrelated orbital disorders.
Coding tip
Verify both the cause and the left-eye laterality in the provider note before assigning H05.422.
